5x+4=9 its an expression which is greater than 1 you can do almost any expression but it has to be more than one.
Hope this helps :D
Answer:
45in³
Step-by-step explanation:
6 x 5 x 3 = 90/2 = 45in³
Since the two equations equal y, set them equal to each other.
x-1=-2x+5
From there, solve for x.
First get x on one side, by using the addition property of equality.
x-1=-2x+5
3x-1=5
Isolate x by adding 1.
3x=6
Lastly get x all by itself by dividing each side by 3.
x=2
You can now substitute your x-value, 2, into one of the equations (or both, if you wish; either one will result in the same answer.)
y=x-1
y=2-1
y=1
OR
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
Final answer:
x=2 and y=1
Any questions or anything you would like me to clarify, feel free to ask :)
Answer:
-2
Step-by-step explanation:
Step 1. Copy the given expression.
(a + y)^2 + 2y =
Step 2. Replace each variable by the value given.
We are given a = 5; y = -3.
= (5 + (-3))^2 + 2(-3)
Evaluate the expression using the correct order of operations.
= (2)^2 - 6
= 4 - 6
= -2
